Brief Analysis of Teaching Model for the Processing of Chinese Materia in Our School / 中国药房

OBJECTIVE:Tosum up the condition of theoretical teaching and experimental teaching of the Processing of Chinese Materia,and to provide referencefor the reform of teaching model of the Processing of Chinese Materia. METHODS:Teaching soft-ware,teaching video and other modelrn teaching methods were used to enrich the content in theory teaching;linking theory with practice was used to stimulate students'interest in learning;scientific research achievement was introduced in teaching to train stu-dents' scientific research thinking;the teaching model of traditional confirmative experiment teaching was reformed by increasing de-signing experiment hours and score;the traditional usual performance evaluation method was changed by replacing with evaluation method of formative,and it was used for evaluation. RESULTS:The students not only learned theoretical knowledge,but also cul-tivated their ability to analyze and solve problems,changing from passive learning to active learning,so that it has made satisfacto-ry teaching effect. CONCLUSIONS:The traditional concept should be changed in teaching of the Processing of Chinese Materia, paying attention to the combination of scientific research and teaching;improve the situation of the designing experiment in the present undergraduate experimental teachingto stimulate students interest in learning,enhance students'practical ability,and im-prove the quality of teaching.

Effect of Different Processes on the Contents of Active Ingredients in Corydalis / 中国中医药信息杂志

Objective To explore the effect of different processes on the contents of active ingredients in Rhizoma Corydalis. Methods Processes of vinegar-boiling, vinegar-frying and alcohol-frying were used to fresh corydalis, boiled corydalis and purchased corydalis. Then the method of extraction by ultrasound with water and by reflux with methanol were used to extract the sample. The contents of Protopine, Tetrahydropalmatine and Dehydrocorydaline in corydalis was determined by RP-HPLC. Agilent TC-C18 (25 mm?4.6 mm, 5 ?m) column was used at 35 ℃, with acetonitrile-0.1% phosphonic acid (pH 5.3 with triethylamine) (28∶72) as mobile phase. The flow rate was 1 mL/min and detection wavelength was set at 280 nm. Results In the sample extracted by water, the contents of active ingredients in processed products were higher than in corydalis. And in the sample extracted by methanol, it also has the tendency that the contents of active ingredients in processed products were higher than in corydalis. The content of Dehydrocorydaline in fresh corydalis which was processed by vinegar-boiling, vinegar-frying and alcohol- frying was high. The content of Tetrahydropalmatine in purchased corydalis which was processed by water-boiling at production place was high. Conclusion The method of determining active ingredients in Rhizoma Corydalis was established. It was convenient and the result was accurate. The process technology that fresh corydalis was boiled by water and then processed or fresh corydalis was processed in production place can be used.
